Ultralow power consumption magnetic induction type floater water level sensor and signal processing method

Abstract

The invention discloses an ultralow power consumption magnetic induction type floater water level sensor and a signal processing method. The floater water level sensor comprises an encoder, a driving gear set, a water gauge range wheel, a counterweight, a steel wire rope and a floater, wherein three magnetic induction reed pipes in 120-degree angular difference are mounted on a fixed code tray of the encoder; two signal wires are led from each reed pipe; a magnet is mounted at the top end of a rotating arm of the encoder; when the magnet passes by the reed pipes, the two output signal wires of the reed pipes are enabled to generate low level; a data collector is roused and the logic state of the signal wires is compared, thereby acquiring a level condition. The ultralow power consumption magnetic induction type floater water level sensor can be used for sensing the change in level in real time, converting the change in level into an electric pulse signal and sending to the data collector, so that the data collector cannot miss the important level change process under a dormant state; the power consumption is low and the sensor can run with zero consumption under most states; the ultralow power consumption magnetic induction type floater water level sensor is especially fit for level real-time collection under field zero alternating current supply condition.

Description

technical field [0001] The invention relates to an ultra-low power consumption magnetic induction float water level sensor and a signal processing method, belonging to the field of hydrology and water conservancy automation. Background technique [0002] In the field of hydrological and water conservancy automation, hydrological telemetry stations are used to collect and remotely transmit original hydrological information, such as rainfall, water level, and flow. A hydrological telemetry station generally consists of various sensors, data collectors, remote communication equipment, and power supply equipment. Among them, the sensor is responsible for converting hydrological information into electrical signals, and the data collector is responsible for collecting these electrical signals and converting them into actual physical values, and sending these data to the data center through remote communication equipment, which is processed and analyzed by the data center.
